Actually, I think Six Sigma would help most of all where you have too many hands dealing with pieces of information. The more "un-needed" human interaction...the more the opportunity for error rises...Six Sigma is notorious for cutting out chunks of bureaucratic information channels.
Considering that I dont know how information is currently processed, I cant give you any idea of how it would change but I think we all know that information has been jammed up based solely on Human judgement...that was catostrophically wrong.
I am sure process' can be put in place to better streamline the flow of information. I dont believe [nor would I think any proponent of Six Sigma] it can replace humint.
Does anyone with an ounce of sense think Six Sigma should replace the Human judgement? Of course not.
Does anyone with an ounce of comprehension of legitimate Six Sigma process' think it will? Of course not.
